This it true, since the latest version I could find anywhere is 1.3.7.
However what I really need is a version compatible with Grails 2.1.1.
The one the contains a version of class HibernatePluginSupport that has the property onChange.

It appears I was looking in the wrong place.
According to findjar.com the class org.codehaus.groovy.grails.plugins.orm.hibernate.H ibernatePluginSupport was in grails-gorm jar.
However in Grails version 2.1.1 it was found in grails-hibernate-2.1.1.jar.
After adding this dependency to .war/lib the problem was solved.
